Abstract: Langer Heinrich Mine (LHM) reports on the operational experiences of thickeners supplied by several vendors. Modifications that were made to mitigate challenges presented by the thickener operation are discussed.
The in-house modifications to the Lightnin® thickener improved capacity, reliability and performance, and the modifications of which, are ongoing. The ANDRITZ Delkor (Pty) Ltd thickener modifications were successful and the thickeners are performing to specification. Indications are that the Roymec Technologies (Pty) Ltd thickeners will perform to specification. The Magra Ultrasep 2000 High Performance Thickener is still in the commissioning phase at the time of writing.
